A journal paper named "All-Links-Based E-Hailing Pricing and Surcharge Mechanism for Transportation System Performance Improvement" in TRR. ( You can find in the attachment)
In the model section (page 5), the author says that "Equations 8-10 are the definitional constraints for the path-link transformation relation and link surcharge calculation mechanisms based on the marginal externality."
I have question about equation 10 (page 5), which is a iterative equation illustrating the link surcharge relationship. But i don't know how to get to this equation. Would anyone like to explain this equation to me.
Thanks!
